Police are turning their efforts to the North Saskatchewan River in the search for a missing Prince Albert boy.

Four-year-old Sweetgrass Kennedy has not been seen since Thursday.

Due to dangers associated with the river bank area, emergency personnel are asking the public and volunteers to avoid the area.

Prince Albert Police are joined by the Saskatoon Police Service Air Support Unit, local fire department and Saskatchewan Emergency Management Fire and Safety in the search effort.

Sweetgrass Kennedy was last seen in the 900 block area of 2nd Street East.

On Friday afternoon, about 100 volunteers gathered as part of a coordinated search effort at a local community centre.

Volunteer Dionne Doucette says with four young children of her own, her heart goes out to the young boy’s family.

“It’s scary, it’s heartbreaking, it’s terrifying – it’s a mother’s worst nightmare,” she says.

Twenty-one-year-old Tanner Mirasty of Muskoday First Nation is also part of the search effort.

With two younger siblings of his own, Mirasty says he wants to help out in any way he can.

“It’s just sad that a four-year-old boy is all alone right now and I’d like to show my support,” he says.

When last seen, the boy was wearing a light blue hoodie and orange Halloween pants.

Police are asking anyone who may have video surveillance of the area to come forward.

They can be reached at 306-953-4254.
